Answer by longjonsilver(2297) (Show Source): You can put this solution on YOUR website!
i take it you mean ? If so, it becomes
solve ..I shall leave out the base, for ease of reading --> .
(x+20)(x-50) = 0
so x+20 = 0 OR x-50=0
so, x=-20 or x=50
in terms of logs, you cannot have negatives, so x=-20 will not be allowed, so x=50 is your one and only answer.
